Environmental Issues For The Twenty First Century And Their Impact On Human Health

The close of the first decade of the 21st century posed additional pressing environmental issues related to human activities and their effects on the planet. The need to protect the planet seems frequently to be in conflict with the need to feed the earth

The most serious environmental problems of the twenty-first century have the potential to alter the course of life on this planet. Global warming, toxic waste, water and air pollution, acid rain, and shrinking energy supplies are frightening challenges that may threaten our future if we do not face up to them.p Global Environmental Challenges provides important information and gives us hope about the environment. This book first helps us to grasp these difficulties, then shows us the choices we can make. How long to leave a light on, whether to take the car, the train, or bicycle to work, whether to recycle or throw away, whether to vote to curb continued suburban sprawl-all of these decisions can make a difference.p This collection of some of the best essays and articles on the environment comes from a variety of sources, including journals, magazines, websites of ecological/conservation organizations, and other publications.p Five major sections investigate the interaction of population growth,consumption, and environment; the emerging crisis in freshwater around the globe; global climate and atmosphere (including global warming); biodiversity loss; and the concept of sustainable development-using natural resources to place future human development on a sustainable path. The final section on sustainable development reveals how we can take action. As individuals, we can make a difference readily and easily without making huge personal sacrifices. As societies, we can work together in a global community of interest to sustain the earth.p This valuable resource offers readers a better understanding of our environmental problems and presents solutions to improving the health of theplanet.p

The aim of this book is to encourage integration of the natural and social sciences with the policy and design-making community, and thereby develop a deeper understanding of complex environmental problems. Its fundamental themes are: • integrated modeling and assessment • complex, adaptive, hierarchical systems • ecosystem services • science and decision-making • ecosystem health and human health • quality of life and the distribution of wealth and resources. This book will act as a state of the art assessment of integrated environmental science and its relation to real world problem solving. It is aimed not only at the academic community, but also as a sourcebook for managers, policy makers, and the informed public. It deals both with the state of the science and the level of consensus among scientists on key environmental issues. The concepts underlying this book were developed at the 2nd EcoSummit workshop held in Halifax, Nova Scotia, June, 2000, with active participation from all delegates, and attempts to present their collective view.

The crucial interdependence between humans and their environment is explored and illuminated in this revealing overview of the major environmental issues facing society in the twenty-first century. With attention to detail and cogent language, the author describes how human health and well-being are inextricably bound up in the web of interrelationships that characterize life on this planet. The presentation combines an overall ecological concern with specific elements related to personal and community health, giving readers a clear sense of how todays environmental issues directly impact their own lives. New to the seventh edition is a chapter on clean energy alternatives that evaluates the long-term potential of the most promising renewable energy technologies as well as short-term strategies to increase energy efficiency. The discussion of global climate change has been significantly updated to reflect the latest assessments of the Intergovernmental Panel on Climate Change with regard to evidence of global warming, mitigation strategies, and adaptation measures, as well as an up-to-date summary of ongoing international efforts to negotiate binding treaties that would produce meaningful reductions in greenhouse gases. Our Global Environment is widely praised by students and faculty for its clear, compelling presentation. Abundant photographs and illustrations highlight salient issues and clarify trends, while boxed inserts in every chapter contain timely examples of general concepts presented in the chapters.

Public and media interest in the climate change issue has increased exponentially in recent years. Climate change, or "global warming," is a complex problem with far-reaching social and economic impacts. Climate Change in the 21st Century brings together all the major aspects of global warming to give a state of the art description of our collective understanding of this phenomenon and what can be done to counteract it on both the local and global scale. Stewart Cohen and Melissa Waddell explain and clarify the different ways of approaching the study of climate change and the fundamental ideas behind them. From a history of climate change research to current attempts to mitigate its impact such as the Kyoto Protocol and carbon trading, they explore key ideas from many fields of study, outlining the environmental and human dimensions of global warming. Climate Change in the 21st Century goes beyond climate modeling to investigate interdisciplinary attempts to measure and forecast the complex impacts of future climate change on communities, how we assess their vulnerability, and how we plan to adapt our society. The book explores the impact of climate change on different ecosystems as well as what the social and economic understanding of this phenomenon can tell us; it also links discussions of climate change with the global discourse of sustainable development. Climate Change in the 21st Century provides a comprehensive, understandable, but academically informed introduction to the world's biggest challenge for both students and concerned citizens.

Environmental engineers support the well-being of people and the planet in areas where the two intersect. Over the decades the field has improved countless lives through innovative systems for delivering water, treating waste, and preventing and remediating pollution in air, water, and soil. These achievements are a testament to the multidisciplinary, pragmatic, systems-oriented approach that characterizes environmental engineering. Environmental Engineering for the 21st Century: Addressing Grand Challenges outlines the crucial role for environmental engineers in this period of dramatic growth and change. The report identifies five pressing challenges of the 21st century that environmental engineers are uniquely poised to help advance: sustainably supply food, water, and energy; curb climate change and adapt to its impacts; design a future without pollution and waste; create efficient, healthy, resilient cities; and foster informed decisions and actions.

From the use of personal products to our consumption of food, water, and air, people are exposed to a wide array of agents each day-many with the potential to affect health. Exposure Science in the 21st Century: A Vision and A Strategy investigates the contact of humans or other organisms with those agents (that is, chemical, physical, and biologic stressors) and their fate in living systems. The concept of exposure science has been instrumental in helping us understand how stressors affect human and ecosystem health, and in efforts to prevent or reduce contact with harmful stressors. In this way exposure science has played an integral role in many areas of environmental health, and can help meet growing needs in environmental regulation, urban and ecosystem planning, and disaster management. Exposure Science in the 21st Century: A Vision and A Strategy explains that there are increasing demands for exposure science information, for example to meet needs for data on the thousands of chemicals introduced into the market each year, and to better understand the health effects of prolonged low-level exposure to stressors. Recent advances in tools and technologies-including sensor systems, analytic methods, molecular technologies, computational tools, and bioinformatics-have provided the potential for more accurate and comprehensive exposure science data than ever before. This report also provides a roadmap to take advantage of the technologic innovations and strategic collaborations to move exposure science into the future.
